\n Researchers at the University of California, San Francisco have devised a nasal spray to administer synthetic antibodies, which they believe will help stop the spread of the coronavirus.<\/p>\n

A team led by graduate student Michael Schoof engineered the synthetic molecules that \u201cstraitjackets the crucial SARS-CoV-2 machinery that allows the virus to infect our cells,\u201d according to a report in the university\u2019s website.<\/p>\n

A paper posted on the preprint server bioRxiv says experiments using the live virus show the molecule is among the most powerful COVID-19 antivirals yet discovered.<\/p>\n

While it\u2019s not a traditional vaccine, the researchers believe one spray a day of the synthetic antibodies, dubbed \u201cAeroNabs,\u201d from a nasal spray or inhales could offer protection from the deadly bug until a vaccine becomes available, according to ABC 7 News<\/a>.<\/p>\n

\u201cBecause it\u2019s so stable we can essentially put in one of these, this is a little nebulizer,\u201d said Dr. Aashish Manglik, an assistant professor of pharmaceutical chemistry UCSF, who added that the aerosolized agents trace back to a minuscule molecule first discovered in camels and similar animals, called a nanobody.<\/p>\n

They\u2019re smaller than human antibodies, and can be manipulated to perform specific tasks. Like attaching themselves to the spike proteins on the coronavirus.<\/p>\n

\u201cIt\u2019s effectively a really effective mousetrap. It binds to one of these spike proteins and never lets go,\u201d Manglik said.<\/p>\n

The researchers pored through about 2 billion synthetic nanobodies before they found the best candidate, which they re-engineered to be even more powerful, the news outlet reported.<\/p>\n

Knowing the coronavirus uses its spikes to attach itself to apart of the lung cell called an Ace2 receptor, they worked to stop the invasion in its tracks.<\/p>\n

When the AeroNabs attach to the spike protein, the virus can\u2019t bind to the receptor and consequently loses its ability to infect cells, ABC 7 News reported.<\/p>\n

\u201cFar more effective than wearable forms of personal protective equipment, we think of AeroNabs as a molecular form of PPE that could serve as an important stopgap until vaccines provide a more permanent solution to COVID-19,\u201d said AeroNabs co-inventor Peter Walter, professor of biochemistry and biophysics at UCSF.<\/p>\n

For people who don\u2019t have access or don\u2019t respond to coronavirus vaccines, Walter added, AeroNabs could be a more permanent line of defense against the disease.<\/p>\n

Manglik, who frequently uses nanobodies in his research on the structure and function of proteins, said: \u201cThough they function much like the antibodies found in the human immune system, nanobodies offer a number of unique advantages for effective therapeutics against SARS-CoV-2.\u201d<\/p>\n

The UCSF team is in discussions with potential partners to ramp up production for clinical trials.<\/p>\n

If successful, the researchers aim to make AeroNabs widely available as an inexpensive, over-the-counter preventative measure or treatment against the coronavirus.\n <\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/div>\n
